Hi Jeff,
            The feedback below is following your question at the IETF 109 meeting on the consideration of MSD in the draft draft-li-pce-pcep-pmtu-03

The definitions of the MSD and the PMTU are as follows,

MSD: Maximum SID Depth - the number of SIDs supported by a node or a link on a node.
Path MTU: The minimum link MTU of all the links in a path between a source node and a destination node.

So MSD is to determine the number of SIDs to be imposed, while MTU can be used by the ingress to determine whether IP fragmentation is needed. The MSD and Path MTU represent different capabilities. In this draft, we focus on the PMTU.

​Warm regards,
Luc-Fabrice
